INTRODUCTION

The AIMS Power 5000 Watt inverters are the most advanced line of mobile DC to AC power systems available. AIMS offers the 5000 Watt inverter in 12V, or 24V, or 36V or 48V DC.

This model is used in a wide range of applications including back up power for remote homes, off-grid systems, RVs, boats, commercial vehicles and mobile businesses. The 5000 Watt inverter will operate most pumps, motors, lights, heaters and hand tools. To get the most out of the power inverter, it must be installed and used properly. Read the instructions in this manual before installing and using this model.

WARNING AND SAFETY

1. Read the manual before connecting this inverter and keep it for future reference.

2. Do not put the inverter under direct sunlight or near a heating source.

3. The case of the inverter will get hot when used. Do not allow flammable materials to contact the

inverter, such as clothing, sleeping bags, carpet or any other flammable materials. The heat from

the inverter can damage these items.

4. The power inverter is designed to be used with a negative ground electrical system! Don't use

with positive ground electrical systems (the majority of modern automobiles, RVs, trucks and

boats are negative ground).

5. Do not disassemble the unit: it may cause fire or electric shock.

6. This device should only be serviced by a qualified technician. This item does not have any serviceable parts.

7. Prevent body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerator enclosures during installation.

8. Do not operate the inverter if under the influence of alcohol or drugs. Read warning labels on prescriptions to determine if your judgement or reflexes are impaired while taking drugs. If there is any doubt, do not operate the inverter.

9. People with pacemakers should consult their physician(s) before using this product. Electromagnetic fields in close proximity to a pacemaker could cause interference to or failure of the pacemaker.

10. Keep the inverter well-ventilated. Do not place any objects on top of or next to the inverter or allow anything to cover the cooling fans; doing so can cause the inverter to overheat, causing a potential fire hazard and/or damage to the inverter. Leave adequate ventilation space underneath the inverter as well; thick carpets or rugs can obstruct air flow, causing the inverter to overheat.

11. Avoid unintentional starting. Be sure the switch is in the OFF position when not in use and before plugging in any appliance.

12. Keep inverter away from children. Don't install the inverter where it is accessible to children. 13. The power inverter will output the same AC power as utility power, please treat the AC outlets

as carefully as you would your home AC outlets. Do not put anything other than an electrical

appliance into the output terminal. It may cause shock or fire.

14. Disconnect the battery and inverter when not in use.

B: Battery terminals: Connect to 12V, or 24V, or 36V, or 48V (depending on inverter model) battery (s) or other DC power source. "+" is positive & " - " is negative. Reverse polarity connection will blow internal fuse and may damage inverter permanently. Make sure you check your input voltage and do not REVERSE POLARITY! This will void the warranty.

C: Chassis ground lug: Connect to earth ground or to vehicle chassis using #8 AWG wire.

Warning! Operation of the inverter without a proper ground connection may result in an electrical safety hazard.

QUICK HOOK-UP AND TESTING

If you would like to quickly hook-up the power inverter and check its performance before going ahead

with your installation, please follow these guidelines:

1. Unpack and inspect the power inverter, check to see that the power switch is in the OFF position.

2. Before you connect the battery cables, make sure the power switch is in the off position. Connect

Red (+) battery cable to Red (+) inverter terminal. Connect Black (-) battery cable to Black (-) inverter

terminal. Connect Red (+) battery cable to Red (+) battery terminal. Connect Black (-) battery cable to

Black (-) battery terminal. Alligator clamp cables may be used but only to connect to the battery. Do not

use clamps on inverter terminals. Alligator clamps are not a permanent solution. You may see a spark

during connection. Do not reverse the polarity. This may damage the inverter and void warranty.

Caution! Loosely tightened connectors result in excessive voltage drop and may cause overheated wires

and melted insulation. Reverse polarity connection will blow a fuse in inverter and may permanently

damage the inverter. Damage caused by reverse polarity connection is not covered by our warranty.

Warning! You may observe a spark when you make this connection since current may flow to charge

capacitors in the power inverter. Do not make this connection in the presence of flammable fumes, as

explosion or fire may result.

3. Set the power switch to the on position. Check the meters and indicators on the front panel of the inverter. The voltage bar graph should indicate 11 to 14 volts depending on the voltage of the power source. If it does not, check your power source and the connections to inverter.

B: Battery terminal (+) B: Battery terminal (-)

C: Chassis grounding

V 2.0

The other indicators should be off.

4. Set power inverter switch to the OFF position, the indicator lights may blink and the internal alarm may sound momentarily. This is normal. Plug the test load into the AC receptacle on the front panel of the inverter. Leave the test load switch off.

5. Set power inverter switch to the ON position and turn the test load on, the inverter should supply power to the load. If you plan to measure the true output R.M.S. voltage of inverter, a meter such as FLUKE 87A, BACKMAN 4410 or TRIPLETT 4200 must be used.

INSTALLATION

1. Where to install

The power inverter should be installed in a location that meets the following requirements:

a. Dry - Do not allow water to drip or splash onto the inverter.

b. Cool - Ambient air temperature should be between 0°C and 40°C, the cooler the better when

operating in this range

c. Ventilation - Allow at least 12 inches of clearance around the inverter for air flow. Ensure the

ventilation openings on the rear and bottom of the unit are not obstructed.

d. Safety - Do not install the inverter in the same compartment as batteries or in any compartment

capable of storing flammable liquids such as gasoline.

2. Cables

DC to AC inverters require high amperage/low voltage DC power to low amperage/high voltage AC

power. To operate properly, connect inverter DC input terminals direct to battery with heaviest wire

available see chart below:

12 Volt Model: 1 x set of 4/0 AWG (1 red + 1black) Recommended: 1ANL500KIT-500Amp fuse kit

24 Volt Model: 1 x set of 1/0 AWG (1 red + 1black) Recommended: 1ANL300KIT-300Amp fuse kit

36 Volt Model: 1 x set of 4 AWG (1 red + 1black) Recommended: 1ANL150KIT-150Amp fuse kit

48 Volt Model: 1 x set of 6 AWG (1 red + 1black) Recommended: 1ANL150KIT-150Amp fuse kit

Battery Cables Installation

When connecting the AC inverter to the battery terminals, it is important to connect the "+" wire to the

"+" terminal and the "-" wire to the “-“ terminal. Do NOT reverse the polarity. It will void the warranty.

Make sure you connect negative to negative and positive to positive.

V 2.0

Caution!

DO NOT allow the wires to cross or touch each other. Install the cables facing away from each other and

screw tightly. When connecting the battery cables to the terminals of the inverter, make sure they do

not touch the case.

3. Grounding

The power inverter has a lug on the rear panel marked "chassis ground" This is to connect the chassis of

the power inverter to the ground.

The ground terminals in the AC outlets on the front panel of the inverter are also connected to the

ground lug.

The chassis ground lug must be connected to a grounding point, which will vary depending on where the

power inverter is installed. In a vehicle, connect the chassis ground to the chassis of the vehicle. In a

boat, connect to the boat's grounding systems in a fixed location, connect the chassis ground lug to an

earth point, which will vary depending on where the power inverter is installed.

The neutral (common)conductor of the power inverter AC output circuit is connected to the chassis

ground. Therefore, when the chassis is connected to ground, the neutral conductor will also be

grounded.

This conforms to national electrical code requirements that separately derived AC sources (such as

inverters and generators) have their neutral tied to ground in the same way that the neutral conductor

from the utility line is tied to ground at the AC breaker panel.

Caution! The Negative DC input of the power inverter is connected to the chassis. DO not install the

power inverter in a positive ground DC system. A positive ground DC system has the positive terminal of

the battery connected to the chassis of the vehicle or to the grounding point.

Warning! Do not operate the power inverter without connecting it to ground. Electrical shock hazard

may result.

OPERATION

To operate the power inverter, turn it on using the ON/OFF switch on the front panel. The power

inverter is now ready to deliver AC power to your loads. If you are operating several loads from the

power inverter, turn on separately after the inverter has been turned on. This will ensure that the power

inverter does not deliver starting currents to all of the loads at once.

1. Controls and indicators

The ON/OFF switch turns the control circuit in the power inverter on and off. It does not disconnect

power from the power inverter.

When the switch is in the OFF position, the power inverter draws no current from battery. When the

switch is in the ON position but with no load, the power inverter draws less than 450 mA.

2. Battery voltage indicator

The battery voltage bar graph indicates the voltage at the input terminals of the power inverter. At low

input current, this voltage is very close to the battery voltage. At high input current, this voltage will be

lower than the battery voltage because of the voltage drop across the cable and connections.

Ideally, the voltage should remain in the green area of the bar graph. If the voltage goes into the red

area at top or bottom of the graph, inverter may shut-down.

3. Battery current indicator

The battery current bar graph indicates the current drawn from the battery by the power inverter, it will

not indicate current by other loads also connected to the battery. The indicator only displays DC volts

and amps.

For long term operation, the current should be in the green area of the bar graph. Short term operation

is possible with current in the orange area. If the current rises to the red area, the inverter will reduce its

output voltage to protect itself.

4. Over temp indicator

The over temp indicator indicates that the power inverter has shut itself down because it has become

overheated. The power inverter may overheat because it has been operated at power levels above its

rating, or because it has been installed in a location which does not allow it to dissipate heat properly.

5. Over load indicator

The over load indicator indicates that the power inverter has shut itself down because its output circuit

has been short circuited or drastically overloaded. Switch the ON/OFF to OFF, correct the fault

condition, and then switch the ON/OFF back to ON.

THINGS TO CONSIDER REGARDING THE LOAD

The 5000W inverter will operate most AC loads within its power rating. When determining whether a

microwave oven can be operated by the 5000W inverter, remember that the power commonly

advertised for microwave ovens is the cooking power (the power delivered to the food) not the power

actually consumed by the microwave oven. The microwave oven will consume 40% to 100% more than

its advertised cooking power. Check the rating sticker on the back of the oven to determine its actual

power draw. The 5000W inverter will operate small microwave ovens (0.2 to 0.3 cubic foot capacity)

that draw is about 1700 watts.

V 2.0

Some induction motors used in refrigerators, freezers, pumps, and other motor operated equipment

require very high surge currents to start. The power inverter may not be able to start some of these

appliances even though their rated current draw is within the rating of the power inverter.

If a motor refuses to start, observe the battery voltage indicator while trying to start the motor. If the

battery voltage indicator drops below 10.5V DC while inverter is attempting to start the motor, this may

be why the motor won't start.

Make sure that the battery connections are good and that the battery is fully charged. If the connections

are good and the battery to is charged, but the voltage still drops below 11 volts, you may need a larger

battery or larger battery bank.

(*2 for 24V *3 for 36V *4 for 48V)

INPUT VOLTAGE

The power inverter will operate from input voltage ranging from 10V-16V, or 20V-32V, or 30V-45V, or

40V-60V depending on model. If the voltage drops below input range, an audible low battery warning

will sound and the voltage indicator will be in the lower red zone. The power inverter will shut down if

the input voltage drops below 10V, or 20V, or 30V, or 40V +/- .5V depending on model. This protects

your battery from being over discharged.

The power inverter will also shut down if the input voltage exceeds 17V/33V/46V/61V +\-.5V. This

protects the inverter against excessive input voltage.

The voltage indicator will be in the upper red zone. Although the power inverter incorporates protection

against over voltage, the inverter is at risk of permanent damage if the input voltage is allowed to

exceed 17V, or 33V, or 46V, or 61V +\-.5V depending on model.

TROUBLESHOOTING

1.Common problems

a. Buzz in audio systems:

Some inexpensive stereo systems and radios will emit a buzzing noise from their loudspeakers when

operated from the power inverter. This is because the power supply in the device does not adequately

filter the modified sine wave produced by the power inverter. The only solution is to use a sound system

that incorporates a higher quality power supply.

b. Television interference:

Operation of the power inverter can interfere with television reception on some channels. If this

situation occurs, the following steps may help to alleviate the problem.

-Make sure that the chassis ground lug on the back of the power inverter is solidly connected to the

ground system of your vehicle, boat or home.

-Do not operate high power loads with the power inverter while watching television.

V 2.0

-Make sure that the antenna feeding your television provides an adequate ("snow free") signal and that

you are using good quality cable between the antenna and the television.

-Move the television as far away from the power inverter as possible.

-Keep the cables between the battery and the power inverter as short as possible and twist them

together with about 2 to 3 twists per foot. This minimizes radiated interference from the cables.
